Trigeminal Neuralgia

Understanding Sudden, Electric Facial Pain

Trigeminal neuralgia causes brief, severe, electric-shock-like attacks of pain in the face, usually on one side. It involves the trigeminal nerve, which carries sensation from the face to the brain. Attacks can be triggered by everyday activities like chewing, talking, brushing your teeth, or a light breeze. Medications control the pain for most people, and several procedures are available when they don't.

Causes

  • Compression of the trigeminal nerve by a nearby blood vessel where the nerve leaves the brainstem (the most common cause).

  • Multiple sclerosis, which can damage the nerve's protective coating.

  • Less commonly, a tumor or other growth pressing on the nerve.

  • Sometimes no cause is found.

Symptoms

  • Sudden, stabbing, electric-shock pain lasting a fraction of a second to two minutes.

  • Pain in the cheek, jaw, teeth, gums, lips, or around the eye, usually on one side.

  • Attacks triggered by touch, chewing, talking, shaving, or wind.

  • Pain-free periods between attacks, which may last weeks or months.

  • In some people, a constant background ache in addition to the attacks.

Imaging Studies to Consider

  • MRI of the brain with special thin cuts through the trigeminal nerve can show a blood vessel pressing on the nerve and rule out multiple sclerosis or a tumor.

Physical Therapy, Home Exercise & Other Conservative Techniques

Physical Therapy

  • Physical therapy has a limited role; gentle jaw and neck care may help when muscle tension adds to pain.

Home Exercise Program

  • Regular low-impact exercise to support overall health and sleep.

Other Studied Techniques

  • Identifying and avoiding triggers when possible (for example, using lukewarm water, a soft toothbrush, or a straw).

  • Protecting the face from cold wind.

Interventional Treatment Options

  • Nerve blocks: Injections of local anesthetic near branches of the trigeminal nerve can bring short-term relief during severe flares.

  • Percutaneous procedures: Radiofrequency ablation, glycerol injection, or balloon compression of the trigeminal ganglion, performed through a needle in the cheek.

  • Stereotactic radiosurgery (Gamma Knife): Focused radiation aimed at the nerve root, with relief developing over weeks to months.

  • Microvascular decompression: A surgical procedure that moves the blood vessel away from the nerve; it offers the most durable relief for suitable candidates. We refer to neurosurgery to discuss it.

  • Platelet-rich plasma (PRP): Evidence is limited to case reports, and PRP is not recommended for trigeminal neuralgia outside a research setting.

Neuromodulation: Spinal Cord & Peripheral Nerve Stimulation

  • Peripheral nerve stimulation: Stimulation of facial nerve branches has been reported in small studies for pain that doesn't respond to other treatment.

  • Spinal cord stimulation is not a standard treatment for trigeminal neuralgia.

Evidence Base: Guidelines & Levels of Evidence

  • Carbamazepine or oxcarbazepine: Level I · European Academy of Neurology trigeminal neuralgia guideline (Bendtsen et al., Eur J Neurol 2019)

  • Microvascular decompression: Level II–III · European Academy of Neurology guideline; large surgical series

  • Radiofrequency, glycerol, balloon, radiosurgery: Level III · European Academy of Neurology guideline

  • Platelet-rich plasma (PRP): Level III · Grade D · ASPN 2024 consensus guideline: not recommended outside research

Evidence levels and guideline citations above are summarized for general clinical reference based on the literature and major society guidelines available at the time of writing. Guidelines are periodically updated; please verify current recommendations before relying on this summary for clinical decision-making.

Pain Psychology Techniques

  • Cognitive behavioral therapy (CBT) for the fear and anticipation of attacks.

  • Mindfulness-based stress reduction.

  • Relaxation training and diaphragmatic breathing.

  • Support for eating and social activities affected by pain.

Non-Opioid Medication Options

Nerve pain (neuropathic) medications

  • Carbamazepine, the first-line medication and the only one FDA-approved for trigeminal neuralgia. It requires blood test monitoring.

  • Oxcarbazepine, often better tolerated.

  • Add-on options include baclofen, lamotrigine, gabapentin, or pregabalin.

Ordinary pain relievers such as ibuprofen or acetaminophen usually don't help trigeminal neuralgia attacks.
